All appears to be set up correctly. Categories loaded ok. Subcategories loaded ok, Products loaded ok. The main page displays correctly at top level.
However, when I click on a top level category which is a group of subcategories I get a repeat of the main page then the category description page.
Conversely when I click on a category which is comprised on products, the main page does not display, instead I get the category description and products list.
The expected outcome is to click on a category page and have its description come up along with the subcategories menu links that are subordinate to that category.
After 4-6 hours of research and tinkering I cannot isolate this problem. Has anybody seen this before. Thanks in advance
